This fuel economy converter helps compare vehicle efficiency units used in different countries and vehicle specifications. It supports US MPG, Imperial MPG, kilometers per liter, liters per 100 kilometers, and US gallons per 100 miles.
Miles per gallon is commonly used in the United States and some other markets. US MPG and Imperial MPG are different because US gallons and Imperial gallons are not the same size.
Liters per 100 kilometers is common in many countries. Unlike MPG, a lower L/100 km value means the vehicle uses less fuel.
Kilometers per liter measures how far a vehicle can travel on one liter of fuel. A higher km/L value means better fuel economy.
A vehicle rated at 30 US MPG is about 7.84 L/100 km. A vehicle rated at 5 L/100 km is about 47.04 US MPG. These conversions make it easier to compare vehicles listed with different regional fuel economy units.
For MPG and km/L, larger numbers are better because the vehicle travels farther per unit of fuel.
For L/100 km and gallons per 100 miles, smaller numbers are better because the vehicle uses less fuel over a fixed distance.
Fuel economy conversions can help estimate fuel usage, compare vehicle efficiency, and understand listings from different countries.
